Gateway Issue with latest version

Im getting the below error when trying to use the latest gateway. Ive used it before so pretty sure I know what im doing (famous last words!) Any ideas?

EDIT: I should probably add, i get this error in the gateway when i try to upload a file. I can open files fine.

Hey, I just tried the gateway from and I was able to use it to upload to us-central with no issues. What OS are you on? And could you provide more info so we can try to replicate?


Im running this on win server, it says… running on version v1.0.0 - this the correct one?

Yeah, I am testing on v1.0.0-rc.6 from here

I will see if anyone can try to replicate this on Windows.

I’m tried to upload via Gateway on Windows

PS C:\Users\USER> aws s3 --endpoint http://localhost:7777 cp .\ s3://test/gateway/
upload: .\ to s3://test/gateway/

PS C:\Users\USER> aws s3 --endpoint http://localhost:7777 rm s3://test/gateway/
delete: s3://test/gateway/

Please, try to use a different bucket

Ive deleted the gateway.exe, rebooted the machine and tried again. Still get the same issue as per screenshot below. Im using the CloudBerry Explorer software as a GUI which has worked in previous versions.

I’m able to reproduce it without this Explorer.

aws s3 --endpoint http://localhost:7777 ls s3://test/gateway

An error occurred (InternalError) when calling the ListObjectsV2 operation (reached max retries: 4): We encountered an internal error, please try again.

In the gateway console:

BTW You can use a minio via browser if you want to have a GUI. http://localhost:7777

thanks @Alexey at least its not just me! Thanks also for the heads up on the browser thing, didn’t know about that!

I created an issue for the team.


This has been added to the next sprint for the user-growth team
